Background of invention
The technical field
The present invention relates to the plates processed by the means for protection against insects and is used as, for example, building boards.
The known technical solutions
Plates used in the construction of buildings must be protected from exposure to insects so that they could not penetrate, for example, termites and other insects.
To make such plates are able to withstand insects usually use the following methods: covering composition containing insecticide, apply a thin layer on the outer surface of the painted steel plate (for example, JP-A-2003-127272); coating containing colloidal silica, gidrofobiziruyuschey additive silane-based tool against ants and similar insects, comprising an aqueous emulsion-based resin is applied on a substrate (for example, JP-A-1999-256076); and the way in which liquid insecticide, adsorbed on silica gel, applied to the surface of the material using a bonding agent (for example, JP-A-2001-158702).
When using the above-mentioned technologies, in which the insecticide is mixed with the coating composition and applied to the surface of the material, a problem arises, namely that the insecticide is diluted resin, which is the OS the ESD component covering composition, and therefore, the concentration of insecticide on the surface of the coating is low, which reduces the actual insecticidal properties of the composition.
Further, when mixing the insecticide with opaque latter after application to the surface of the material is usually subjected to a drying heat in the temperature range between 100°150°With which may cause changes in the properties and fracture of the insecticide.
When using technology, in which particles of silica gel with adsorbed liquid insecticide is applied to the surface of the material using a bonding agent, it is possible the separation of particles of silica gel the surface of a bonding agent that makes it difficult to provide long lasting insecticidal effect.
As a solution to the above problems according to the present invention proposed stove, protected from exposure to insects by applying to the surface of the cover plate on the basis of the applied coating, chemical processing solution containing the insecticide in the composition of the aqueous dispersion of colloidal silica.
Usually insecticidal processing solution prepared by adding an insecticide to the dispersion of colloidal silica in a water-alcohol solvent. In this case, preferably, the addition of surface-active is about substance as a dispersing agent in the dispersion of colloidal silica in aqueous alcoholic roscovitine.
Method of implementation
Insecticidal machining solution in this invention is a liquid processing that adds the insecticide in an aqueous dispersion of colloidal silica, and the liquid does not contain the covering composition, which would contain a resin as a main component, and, therefore, the insecticide is not diluted resin and firmly connected to the microscopic irregularities of the convexo-concave surface of colloidal silica and colloidal silica are enshrined in the coating layer on the substrate surface via hydrogen bonds.
In accordance with the present invention, the insecticide is present in high concentrations on the surface covering the basics in colloidal silica role environment that provides a high insecticidal effect and allows you to get a plate having significant insecticidal activity even when using small amounts of insecticide. In addition, since the insecticide is firmly connected to the surface through the medium of the colloidal silica used as the medium, it allows you to get long lasting insecticidal effect.
Detailed description of the invention
Below is a detailed description of the invention.
Substrate (workpiece material)
Yes the Noah invention can be applied to the following materials: cement slabs (cement boards with a wood-fibrous filler), reinforced wood shavings, wood mass, wood fiber, etc., cement plate obtained by the extrusion molding, cement boards with a wood lot, drywall sheets, plates based on calcium silicate, plate-based magnesium carbonate, multi-layer wood, wood-fiber Board, MDF, steel sheets, metal construction plates, etc.
The coating applied to the surface of the base (protected material). Usually applied multi-layer coating comprising a binder layer, intermediate layer, the upper layer and transparent coating. It is recommended to use water-based opaque composition, for example aqueous emulsion of acrylic resin or silicon-acrylic resin for the binder layer, the intermediate layer, the upper layer and transparent coating. However, it can be used covering the composition-based solution, for example a composition on the basis of transparent acrylic solution resin, and can also be used in combination with water-based opaque composition and opaque composition-based solution.
Insecticidal processing solution
Colloidal silica as a component of insecticide treatment solution described in this invention, is a substance with the following structure: approximately 10 primary fine particles with a diameter of 5 to 1 nm form secondary fine particle with the formation of microscopic convexo-concave patterns on the surface. The colloidal silica may contain small amounts of other components, such as aluminum oxide and silicon dioxide.
In the present invention preferably adding alcohol into the water, which serves as the dispersion medium for the colloidal silica. It is desirable to use a water-soluble alcohol, such as methanol, ethanol or isopropanol. Alcohol reduces the surface tension of the insecticidal treatment solution described in this invention, and increases the affinity of this solution to the underlying layer of the coating, which improves the wettability insecticidal processing solution.
Further according to this invention is preferably added in insecticide machining solution of surface-active substances (surfactants) as a dispersing agent. As the surfactant can be any of the commonly used anionic, nonionic and cationogenic surfactants. As anionic surfactants can be used sulfates of higher alcohols (in the form of sodium salts, or amines), alkyl sulphonates (sodium salt or amine), alkylnaphthalene (in the form of sodium salts, or amines), condensates alkylnaphthalenes, alkylphosphate, diallylmalonate, resin Soaps and salts of fatty acids (sodium salt or amine). As nonionic surfactants which may be used polyoxyethylene alkyl esters, polyoxyethylene alkylphenol esters, complex polyoxyethylene esters, polyoxyethylene the bonds alkylamines, polyoxyethylene alkylolamides amines, polyoxyethylene alkylamine, alkyl esters of sorbitol and polyoxyethylene alkyl esters of sorbitol. As cationogenic surfactants may be used octadecylamine, acetates derivatives of imidazoline compounds, derivatives of polyallylamine and their salts, octadecyltrimethoxysilane ammonium halides of Triethylenetetramine, alkyl sulphates of pyridium and halides of alkyltrimethylammonium. Can be used in mixture of two or more surfactants. The following list of examples is not exhaustive.
The mixture of surfactants with alcohol reduces the surface tension in insecticide manufacturing solution described in this invention, the proper way contributes to the dispersion of colloidal silica in insecticide solution and increases the affinity of insecticide solution to the underlying layer of the coating.
Insecticidal processing solution described in the present invention usually contains from 0.1 to 2.0 mass% of colloidal silica, from 2 to 10 weight percent alcohol, from 0.01 to 0.25 weight percent surfactant, and an appropriate amount of water.
When the alcohol content below two mass percent smace haemost insecticidal treatment solution deteriorates, while when the alcohol content exceeds 10 mass%, increased evaporation of the solvent, which is unfavourable from the point of view of the coating process. When the surfactant content below 0.01 mass%, the effect of reducing the surface tension and the effect of dispersion of colloidal silica be negligible, if the content of the surfactant exceeds the 0.25 mass%, the film forming insecticidal coating will not have the necessary strength, waterproof, stability, etc. Thus, it is necessary to insecticidal machining solution had a surface tension of not higher than 20 Dyne/cm at 25°C.
Insecticide part of insecticidal treatment solution, can be selected by a specialist, depending on specific tasks, operating conditions, type of insects that live in any climate zone, etc. Insecticide preferably selected from compounds of pyrethroids for human security. Among the possible connections of this type can be mentioned permethrin, allethrin, tralomethrin selflove, block Atofina, phenothrin, etc. Other known classes of insecticides previously used or currently in use to protect building materials (particularly wood), which may be used within the present invention. For example, known organochlorine insecticides with high activity and resistance to decomposition, which, in spite of the increased toxicity, can still be used in some cases. Materials treated with these insecticides, can be widely used for the construction of structures that are not designed to live and work in them (containment, transformer substations and the like) in regions with high biological corrosion". In addition, insecticides, widely used in household chemicals (from moths, the tools used for removing fleas and ticks in Pets, etc), can also be successfully used for protection of construction materials.
The content of the insecticide insecticide manufacturing solution is usually from 0.01 to 5 mass percent.
The use of insecticidal treatment solution
After the coating process the coating material is usually subjected to a drying process by heating to a temperature of 100-150°C. After drying the coating by heating the treated material is cooled to normal temperature. Insecticidal machining solution start to apply after the temperature of the coating is lowered to not more than 80°S, and preferably to not more than 70°Spri temperatures above there is no risk of thermal destruction of insecticide. Although insecticidal machining solution is usually applied by sputtering technique, can be used by other known methods, for example, using gruntovalnoy machine or roller device.
Restrictions on the number of the applied substance is not installed, although it is usually used as much of the solution as needed to obtain the thickness of the insecticidal coating in the range from 30 to 80 nm after coating and drying.
Below are examples that illustrate the essence of the present invention in more detail.
Were prepared following insecticidal machining solutions.
|Insect. arr. R-R 1||Insect. arr. R-R 2|
|Colloidal silica (size of secondary particles: 5 μm)||2 mass%||2 mass%|
|Insecticide (permethrin)||0.2 mass%||0.02 mass%|
|Ethanol||4 mass%||4 mass%|
|Surfactant*||0.02 mass%||0.02 mass%|
On the surface of drives the fiber cement boards, to be processed, sprayed coating consisting of a binder layer, intermediate layer and top layer (composition is an aqueous emulsion of acrylic resin), and then clear coating based on an acrylic solution resin, after which the dried material by heating in the quenching furnace to a temperature of 100-110°C.
After drying the heat treated material was removed from the surface of the furnace and cooled at room temperature. After the temperature of the surface of the transparent cover has dropped to 65°With, on this surface by sputtering technique was applied insecticide machining solutions 1 and 2. After that, the processed material was left at normal temperature, in order to give insecticidal solution to dry due to the residual heat of the transparent cover. Thus, there was formation of insecticidal layer thickness of 50 nm on the two samples (with insecticidal processing solutions 1 and 2, respectively).
For the comparative analysis made, the following are a few samples: a comparative sample 1 without applying insecticidal treatment solution (untreated sample); comparative sample 2, in which the treated material was applied clear coating containing 0.2 mass% permethrin; comparative sample 3, in which permer the n was applied directly to the surface of the processed material; and comparative sample 4, in which the insecticidal machining solution 1 was applied onto the material being processed is similar to sample 1, and the surface temperature of the coating was 80°C.
The duration of insecticidal effect was evaluated on samples 1, 2 and comparative examples 1-4.
Method of assessment consistent with test method approved by the Japanese centre of communal hygiene.
Insecticidal effect on each sample was measured immediately after application and drying insecticidal treatment solution, after the processed material has been outdoors for 40 days and after he had been outdoors for 6 months. The experiment was started on 1 may 2004 and completed after 6 months, i.e. on 1 November 2004.
The evaluation results are shown in Table 1.
|Immediately after applying the||40 days||After 6 months|

|Comparative Sample 2||97.9||88.6||68.4|
|Comparative Sample 3||100||87.4||61.4|
|Comparative Sample 4||89.7||81.2||71.1|
Insecticidal effect (%) was calculated based on the following equation 1.
*control sample: a comparative sample 1
The data in Table 1 demonstrate that the insecticidal effect in samples 1 and 2 differed only slightly, and that in both samples good insecticidal effect was maintained for even more than 6 months. Thus, it was established that the number of used insecticide and insecticide effect no significant correlation.
For comparative sample 2, in which the insecticide was added to the coating composition, it was found a significant reduction in insecticidal effect after 6 months. With regard to the comparative sample 3, in which the insecticide was applied directly on the surface of the material, it was found more significant reduction in insecticidal effect after 6 months. With regard to the comparative sample 4, in which the insecticidal machining solution 1 was applied at a temperature p is the surface coverage, 80°To be installed destruction of the insecticide under the influence of heat, resulting insecticidal effect in this sample was lower than in sample 1.
